Experimentology is out today!!! A group of us wrote a free online textbook for experimental methods, available at experimentology.io - the idea was to integrate open science into all aspects of the experimental workflow from planning to design, analysis, and writing.
Experimentology cover: title and curves for distributions.

Great study! Really interesting that the previous findings are now reversed. We need more replication (& extension) studies like this in the social sciences!

My co-authors and I just published a paper!

Our questions?🤔

(1) Whether a gender bias that was first documented 20 years ago would replicate, and if so...

(2) Whether its magnitude would depend on whether the women in question were Black rather than White.

Seems the White House is using gen AI to write their scientific reports, leading to the hallucinations and mistakes you'd expect. Laughing/crying right now.

Climate Terminology Does Not Matter

Across tens of thousands of participants in two large-scale experiments, we found that labeling climate change in different ways had no effect on their stated willingness to act.

Climate Terminology Does Not Matter
Our new paper finds that swapping out one climate term for another does not meaningfully change people’s stated commitment to fight climate change

Chegg, notorious resource for student cheating, is mad that Google is copying its answers.

Edtech company Chegg has filed a lawsuit against Google and its owner Alphabet, alleging that the search giant’s #AI Overviews hurt its online traffic. According to Chegg, the Overviews retain traffic that historically came to its website, “materially impacting” the company’s revenue and employees.

IMPORTANT: If you live in the United States or Canada, you’ve probably heard Trump‘s constant claim that the United States is “subsidizing” Canada. It’s wrong of course, but here’s the best explanation I’ve seen about how & why it’s wrong. PLEASE WATCH & SHARE IT A LOT. Kudos to Andrew Chang & CBC.

Underreported: Elon just picked the head of NASA—a massive conflict-of-interest that will damage a government entity that he partners with, depends on, and in some cases competes with. The nominated NASA director is a high-school dropout billionaire who is pals with Musk. He has no business at NASA.

Intertemporal choice questions are usually like "Receive $10 now, or $15 next month?" Yet real-life decisions usually involve a mix of negatives and positives. Do mixed-valence questions better predict real-life behaviours? No! go.shr.lc/3OG36rz

the fallout from the Francesca Gino research misconduct scandal isn't over. @engber.bsky.social writes about how an effort by some of her colleagues to self-audit their work with her ended up raising even more questions — for them personally and their whole field www.theatlantic.com/magazine/arc...

The superendowment effect—research by Winegar and Sunstein finds users would demand $80 to share personal data, but pay only $5 to keep them private. This raises questions over the reliability of WTP/WTA to gauge the welfare significance of giving up or maintaining privacy: https://buff.ly/3Oa5jvr

It’s insane that I got all the way through getting a PhD before I encountered equivalence tests. These should be part of every intro stats curriculum that covers NHST.
